 Physics Preliminary Summary: Measurements of the groomed jet radius and groomed momentum fraction in pp and Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV /ALICE Collaboration We report jet substructure measurements in pp and Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV with the ALICE detector. The groomed jet momentum fraction, $z_\rm{g}$, and the groomed jet radius, $\theta_\rm{g} \equiv R_\rm{g}/R$, are measured using the Soft Drop grooming algorithm.

 Future high-energy pp programme with ALICE /ALICE Collaboration This document presents the proposal of the ALICE Collaboration for an extended data taking programme with high-energy proton-proton collisions ($\sqrt s \approx 13$--14~TeV). The proposed programme includes two components: a sample with a target integrated luminosity of about 200 pb$^{-1}$, for which a highly-selective software-based event skimming will be performed after data reconstruction, and a minimum bias sample with a target integrated luminosity of about 3 pb$^{-1}$.

 Supplemental figures: "Transverse-momentum and event-shape dependence of D-meson flow harmonics in Pb-Pb collisions at ${\sqrt{s_{\rm{NN}}} = 5.02}$ TeV" /ALICE Collaboration The following public note presents supplemental figures for the paper "Transverse-momentum and event-shape dependence of D-meson flow harmonics in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}} = 5.02$ TeV"~\cite{Acharya:2020pnh}. The elliptic ($v_2$) and triangular ($v_3$) flow coefficients of prompt non-strange D mesons were measured at midrapidity ($|y|<0.8$) in the transverse momentum interval $1< p_{\rm T} <36$ GeV/$c$ in central (0-10\%) and semi-central (30-50\%) Pb-Pb collisions at the centre-of-mass energy per nucleon pair of $\sqrt{s_{\rm NN}}$=5.02 TeV with the ALICE detector at the LHC.

 Groomed jet substructure measurements of charm jets tagged with $\rm{D}^{0}$ mesons in pp collisions at $\sqrt{s}$ = 13 TeV /ALICE Collaboration The ALICE collaboration at the CERN LHC reports the first measurements of groomed jet substructure observables for jets containing a fully reconstructed $\rm{D}^{0}$ in pp collisions at $\sqrt{s}$ = 13 TeV. Iterative declustering techniques access the jet splitting tree of track-based jets, with grooming techniques isolating the perturbative branches.

 Data-driven model for the emission of spectator nucleons as a function of centrality in Pb-Pb collisions at LHC energies /ALICE Collaboration At colliders the Zero Degree Carimeters (ZDC) measure mainly the energy carried by free'' spectators, namely the fragments are not bound in fragments after the collision. The most commonly used event generators for nucleus-nucleus collisions do not include a reliable model to describe the formation of nuclear fragments.

 A Forward Calorimeter (FoCal) in the ALICE experiment /ALICE Collaboration We discuss a forward electromagnetic and hadronic calorimeter (FoCal) as a possible upgrade to the ALICE experiment, which could be installed during LS3 for data-taking in 2026–2028 at the LHC. The FoCal is a highly granular Si+W electromagnetic calorimeter combined with a conventional sampling hadronic calorimeter covering pseudorapidities of 3.2 < $\eta$ < 5.8.

 Second order event plane dependence of jet-hadron correlations in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV /ALICE Collaboration In the paper linked to this note, we reported the yields, yield differences, yield ratios, widths of jet-hadron correlations relative to the reaction plane in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV for reconstructed jet transverse momenta 20 < $p_{\rm{T}}^{\rm{jet}}$ < 40 GeV/$c$ as a function of the angle between the reconstructed jet and the reaction plane. A sample correlation function was shown in the paper for associated particles with momenta 20 < $p_{\rm{T}}^{\rm{assoc}}$ < 40 GeV/$c$. [...] ALICE-PUBLIC-2019-004.- Geneva : CERN, 2019 - 21.

 Supplemental figures: $^{3}_{\Lambda}\mathrm{H}$ and $^{3}_{\overline{\Lambda}}\mathrm{\overline{H}}$ lifetime measurement in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}} =$ 5.02 TeV via two-body decay /ALICE Collaboration The following note presents supplemental figures for the paper: $^{3}_{\Lambda}\mathrm{H}$ and $^{3}_{\overline{\Lambda}}\mathrm{\overline{H}}$ lifetime measurement in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}} =$ 5.02 TeV via two-body decay \cite{Acharya:2019tauh3l}. The (anti-)\hyptriton lifetime has been measured by analyzing the data sample of Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}} =$ 5.02 TeV with two methods: the exponential fit to the d$N$/d($ct$) spectrum and the unbinned fit.
